Drained Soil Modulus from Load Tests for Shallow Foundation Design

Akbas, Sami O. / Kulhawy, Fred H.

Elastic theory is used to back-calculate the drained secant soil modulus from loads and settlements measured in full-scale load tests on footings in axial compression. The moduli are evaluated at L₁ (the end of the initial linear region) and at a settlement of 1% of the foundation width. These drained soil moduli are normalized by standard penetration test results at each site, and the normalized values are correlated effectively with the soil stress history, stress state, and stress level. The resulting correlations will be useful for footing design.
